Sadly, it is not uncommon for Muslims to treat the canonical Prayers as a mere ritual (having little effect on one’s life and by extension in the society). There are Muslims who will
commit fraud and theft, engage in gossip and slander and rape and murder and etc [in some cases they often perceive their actions justified and virtuous] even in the name of religion. Yet they are steadfast in their canonical Prayers and deem themselves as
pious or practicing Muslims due to their performance of rituals. They may have performed ‘Salah’ according to the conditions of dogmatic religion or the precepts of the clergy, but have they upheld the Salah by the precepts of God - the
Exalted, according to the Quran.
Utlo (read, understand, adopt and propagate) what has been revealed to you from Al-Kitab and establish As-Salat.
Verily, As-Salat prevents from Al-Fahisha and Al-Munkar. And surely Zikr (Message) of Allah (is something) Greater. And Allah knows what you people do and invent. (Quran 29:45, transl.
Dr K. Omar)
I—I am God. There is no God but I. So serve Me, and practice the prayer for
My remembrance. (Quran 20:14, transl. T.A. Itani).
Say: "Behold, my prayer, and (all) my acts of worship, and my living and my dying
are for God [alone], the Sustainer of all the worlds, (Quran 6:162, transl. Asad).
True piety does not consist in turning your faces towards
the east or the west - but truly pious is he who believes in God, and the Last Day; and the angels, and revelation, and the prophets; and spends his substance - however much he himself may cherish - it - upon his near of kin,
and the orphans, and the needy, and the wayfarer, and the beggars, and for the freeing of human beings from bondage; and is constant in prayer, and renders the purifying dues; and [truly pious are] they
who keep their promises whenever they promise, and are patient in misfortune and hardship and in time of peril: it is they that have proved
themselves true, and it is they, they who are conscious of God. (Quran 2:177, transl. Asad)
Furthermore, at every instance where believers are requested
to uphold the Salah in the Quran – the surrounding [if not within the] verses mention the injunctions and directives of God to be applied by the believers as if to say that the Salah has a direct correlation to serving God beyond the ritual service.
A pertinent question to ask is - have the Muslims lost the essence of the Salah after a long time had
passed, like the previous generations of believers?
But they were succeeded by generations who [Arabic: aDaa’u] neglected/wasted/ruined
the Salah and pursued their own desires so they will meet with utter disillusionment – (Quran 19:59)
And God knows best.
 Such as in the heat of the battle: Quran 17:5, 21:80, 33:18, 48:16 and violence
16:81, 59:14 etc.
 The examples are too many. The reader is encouraged to read the Quran for themselves. The directive to establish Salah: - 10:87; 11:114; 14:31; 14:37; 14:40; 17:78; 2:110; 2:277; 2:3;
2:43: 2:83; 20:14; 22:35; 22:41; 24:56; 27:3; 29:45; 30:31; 31:17; 31:4; 35:29; 4:77; 42:38; 5:12; 5:55; 58:13; 6:72; 7:170; 73:20; 8:3; 9:11; 9:5; 9:71; 98:5
